What you are doing is printing the value in the array at spot [3][3], which is invalid for a 3by3 array, you need to loop over all the spots and print them.
for(int i = 0; i < 3; i++) {
for(int j = 0; j < 3; j++) {
printf("%d ", array[i][j]);
}
printf("\n");
}
This will print it in the following format
10 23 42
1 654 0
40652 22 0
if you want more exact formatting you'll have to change how the printf is formatted.

There is no .length property in C. The .length property can only be applied to arrays in object oriented programming (OOP) languages. The .length property is inherited from the object class; the class all other classes & objects inherit from in an OOP language. Also, one would use .length-1 to return the number of the last index in an array; using just the .length will return the total length of the array.
I would suggest something like this:
int index;
int jdex;
for( index = 0; index < (sizeof( my_array ) / sizeof( my_array[0] )); index++){
for( jdex = 0; jdex < (sizeof( my_array ) / sizeof( my_array[0] )); jdex++){
printf( "%d", my_array[index][jdex] );
printf( "\n" );
}
}
The line (sizeof( my_array ) / sizeof( my_array[0] )) will give you the size of the array in question. The sizeof property will return the length in bytes, so one must divide the total size of the array in bytes by how many bytes make up each element, each element takes up 4 bytes because each element is of type int, respectively. The array is of total size 16 bytes and each element is of 4 bytes so 16/4 yields 4 the total number of elements in your array because indexing starts at 0 and not 1.

November 28, 2020New to C array printing weird numbers
Two problems: You're trying to loop from 0 <= i <= n+1, but the array only contains n items, so you'll only have indices 0 to n-1. Generally, we'd write this range as 0 <= i < n. sizeof an array returns its size in bytes, not elements. Since ints are (usually) 4 bytes large, you're getting 4 times the size you expect. You need to divide the size of the whole array by the size of each individual element, like so: sizeof(arr) / sizeof(arr[0]). The "weird numbers" are caused by reading memory outside of your array. What's in that memory is undefined, and you could potentially crash your program by reading too far out of bounds, since you might hit memory that doesn't belong to you. More on reddit.com

September 22, 2021Loop over array elements without knowing length
Either your array is static or it's dynamic. If the array is static you know its length even if you don't explicity set it to a known length. You can do this int array[] = {1, 2, 3, 4, 5, 6, 7, 8, 9, 10}; const int ARRAYLEN = (sizeof(array) / sizeof(array[0])); Use the ARRAYLEN value in your code. If the array is dynamic (malloc(), etc) you need to keep track of the array size, there's no other way. More on reddit.com

You have to print each element individually; C doesn't have a built-in way to print the entire array at once. An array in C is just a sequence of objects of a given type; there's no metadata to tell you the number of elements, their type, etc. Array expressions "decay" to a pointer to their first element, and that pointer doesn't give any of that information either. Operations on arrays are limited. Array expressions cannot be the target of an assignment; you can't write something like int arr[5]; arr = {0, 1, 2, 3, 4}; // NOT ALLOWED You would have to assign each element individually: for (int i = 0; i < 5; i++ ) arr[i] = i; or use the memcpy or strcpy (for strings) library functions: memcpy(arr, (int []){1, 2, 3, 4, 5}, sizeof arr); Array sizes are fixed; you can't add or remove elements at runtime. There's no "slicing" operation where you can easily grab a subset of the array. In short, they're not like lists at all.

In this modified code, we have added a variable named max to store the maximum element of the array. We then use a for loop to iterate through the array and compare each element with the current value of max. If the current element is larger than max, the value of max is updated. Finally, we print the value of max.
